How to Fix CVE-2025-43749

To remediate this vulnerability, upgrade all affected Release.portal.bom dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.liferay.portal:release.portal.bom fixed: Latest secure release 
<dependency>
    <groupId>com.liferay.portal</groupId>
    <artifactId>release.portal.bom</artifactId>
    <version>Latest secure release</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.liferay.portal

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-43749, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.liferay.portal

Analyze the terminal output to locate any version of Release.portal.bom in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.liferay.portal command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
